gba gsm audio player improved
this version allows album art.
I think it also allows you to drop in wavs? the other music player required sox conversation and I always forget the command maybe this will be easier.
m8 tracker is ios native
40$ cad
been thinking about picking up

Midi Program Changer
Midi Program Changer github
Made this in python to change programs with the plus and minus keys on a qwerty keyboard. The easiest way to use is run the linux x86 build on github that I packaged together with pyinstall so you dont need to manually deal with dependencies. Otherwise if your own win/mac heres the python.
